With the large-scale development and utilization of new energy in China, the construction of pumped storage power stations has also accelerated significantly, and in the 21st century, the construction of pumped storage power stations in China has entered the fast lane
.
The installed capacity put into production increased from more than 5 million kilowatts to 21.
85 million kilowatts in 2014, second only to Japan and the United States
.
At present, the capacity under construction is 21.
28 million kilowatts, ranking first
in the world.
It is expected that by the end of 2015, China's pumped storage capacity will exceed that of the United States, and the end of the "Thirteenth Five-Year Plan" will surpass Japan
.
Compared with the developed countries in the world, China's pumped storage installed capacity is obviously insufficient, far from meeting the needs of China's rapid economic and social development and safe and stable economic operation of the power system, and cannot meet the needs of the large-scale development of UHV power grid, energy conservation and emission reduction of power system, large-scale long-distance transmission of clean energy, and large-scale access of distributed generation
.
At present, China has begun to take the lead in carrying out the independent development and application research of pumped storage equipment, realizing the fundamental leap of the key technology and complete set of equipment manufacturing industry of pumped storage units in China from scratch and from weak to strong, and the excitation, speed regulation and frequency conversion systems of 100-megawatt-level domestic pumped storage units have been successfully put into operation in Xiangshuijian Power Station, breaking the long-term monopoly
of foreign enterprises in this field.
Up to now, although China's pumped storage power stations have covered the north and south of the river, and there are more medium and large pumped storage power stations throughout the country, the capacity of pumped storage power stations accounts for a small proportion of the total installed capacity of power generation in the country, and there is still a lot of room
for development in the future.
